Description

Technical Field

[0001] This utility model relates to the field of garage roller door technology, specifically to an easy-to-install garage roller door. Background Technology

[0002] Garage roller doors are a type of door widely used in residential, commercial, and industrial buildings, primarily for garage openings. They open or close the garage by rolling up or down the curtain using a roller. Garage roller doors typically consist of a curtain, roller, guide rails, motor, and control system. The curtain is made of various materials, including metal, plastic, wood, or composite materials, designed to provide functions such as security, heat insulation, and sound insulation. The guide rails guide the curtain's lifting path, ensuring smooth operation, while the motor and control system are responsible for the automated operation of the curtain, making it convenient for users.

[0003] The installation of existing garage roller doors involves many cumbersome steps, especially the connection and fixing of multiple components. Traditional installation methods often require a large number of bolts and hinges to connect the various parts of the door curtain and fix the guide rail to the wall and ceiling. These steps are not only time-consuming and labor-intensive, but also increase safety hazards during the long installation process when working at height.

[0004] In view of the above, this application is hereby submitted. Utility Model Content

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see the appendix Figure 1 To be continued Figure 7 This utility model provides an easy-to-install garage roller door: including a wall 10 and a ceiling 11 fixed to the top of the wall 10. The length directions of the wall 10 and the ceiling 11 are perpendicular to each other. Guide rails 12 are fixed at both ends of the sidewalls of the wall 10 and the ceiling 11 that are close to each other. Several baffles 20 are slidably provided on the side of the two guide rails 12 that are close to each other. Connecting mechanisms are provided at both ends of the sidewalls 20 that are close to each other. The connecting mechanism includes several fixing rings 22 that are evenly distributed along the length direction of one baffle 20 and fixed on one baffle 20. Several fixing rings 23 that are evenly distributed along the length direction of the other baffle 20 are fixed on the other baffle 20. The fixing rings 22 and the fixing rings 23 are staggered.

[0031] When two adjacent baffles 20 abut against each other, several fixing rings 1 22 and several fixing rings 23 are coaxially arranged. The several fixing rings 1 22 and several fixing rings 23 are provided with the same limiting rod 1 24 and the same limiting rod 25. A fixing rod 26 is fixed at the center of the side wall of the limiting rod 25 near the limiting rod 1 24. A stop block 28 is fixed at the end of the fixing rod 26 near the limiting rod 1 24. A stop block 27 slides on the side of the fixing rod 26 near the limiting rod 1 24. A groove 1 is provided at the center of the side wall of the limiting rod 1 24 near the limiting rod 25. Grooves 2 are opened on opposite sides of the inner arc wall of groove 1. A limiting rod 3 29 slides in groove 2.

[0032] The first stop 27 and the second stop 28 have the same structure. The longitudinal section of the first stop 27 along the axis of the fixed rod 26 is trapezoidal. The inclined surfaces on the outer arc walls of the first stop 27 and the second stop 28 are inclined towards the side that is far away from each other. The end of the third limiting rod 29 near the inside of the first groove is an inclined surface, and the inclined surface at the end of the third limiting rod 29 is complementary to the inclined surface of the outer arc wall of the second stop 28. Rollers 21 are rotatably connected to the bottom of both sides of the baffle 20 along its length direction. The rollers 21 rotate within the guide rail 12.

[0033] There is a gap between the first stop block 27 and the second stop block 28. A return spring 1 is fixed on the side of the first stop block 27 away from the second stop block 28. The end of the return spring 1 away from the first stop block 27 is fixed to the second limit rod 25. A return spring 2 is fixed on the side wall of the third limit rod 29 near the second groove. The end of the return spring 2 away from the third limit rod 29 is fixed to the inner side wall of the second groove away from the first groove. A third groove is provided on the side of the outer arc wall of the first limit rod 24 and the second limit rod 25 away from the baffle 20. The length direction of the third groove is consistent with the radial direction of the first limit rod 24. A limit block is provided in the third groove.

[0034] It should be noted that: multiple baffles 20 are interconnected through a connecting mechanism. Each baffle 20 has a fixing ring 22 at one end and a fixing ring 23 at the other end. The fixing rings 22 and 23 of two adjacent baffles 20 are staggered. When two baffles 20 abut against each other, their fixing rings 22 and 23 are coaxially aligned. At this time, the limiting rods 24 and 25 can be inserted from both ends respectively.

[0035] When the limiting rod 1 24 and the limiting rod 25 are inserted into the hollow cylinder composed of the fixing ring 1 22 and the fixing ring 23, the fixing rod 26 enters the groove 1, and the inclined surface of the end of the limiting rod 3 29 abuts against the arc wall of the stop block 28, forcing the limiting rod 3 29 to retract. When the limiting rod 3 29 passes the stop block 28, the limiting rod 3 29 pops out under the action of the return spring 2. In this state, since the side walls of the limiting rod 3 29 and the stop block 28 that are close to each other are both vertical planes, the limiting rod 1 24 and the limiting rod 25 are locked to each other at this time, and the limiting block further prevents the limiting rod 1 24 or the limiting rod 25 from leaving the hollow cylinder.

[0036] To release the fixation, simply continue moving the first limit rod 24 or the second limit rod 25 toward the side that is closer to each other. When the third limit rod 29 abuts against the first stop 27, the inclined surface at the end of the third limit rod 29 abuts against the edge of the first stop 27, forcing the third limit rod 29 to retract. Here, the friction between the third limit rod 29 and the first stop 27 is less than the elastic force of the first return spring. However, when the first return spring is compressed to a certain extent, the thrust transmitted from the third limit rod 29 is greater than the elastic force of the first return spring, causing the third limit rod 29 to pass over the first stop 27. At this time, move the first limit rod 24 or the second limit rod 25 toward the side that is farther away from each other, and the third limit rod 29 will carry the first stop 27 to move in the opposite direction.

[0037] When stop block 1 27 and stop block 28 abut against each other, limit rod 3 29 can slide unimpeded along the outer arc wall of the two, and limit rod 1 24 and limit rod 25 then separate, and stop block 1 27 is reset under the action of return spring 1.

[0038] Please see the appendix Figure 1 To be continued Figure 7 The present invention provides a technical solution: a limiting plate 15 is sleeved on the outer side of the guide rail 12 near the ceiling 11, a hanger 14 is fixed on the side wall of the limiting plate 15 near the ceiling 11, and the end of the hanger 14 away from the limiting plate 15 is fixed on the ceiling 11. A guide rail 13 is fixed at the bottom of the ceiling 11 between the two guide rails 12, and the length direction of the guide rail 13 is consistent with the width direction of the wall 10.

[0039] The limiting plate 15 and the guide rail 12 are respectively provided with a rotating groove 1 at the center of the side wall of the guide rail 2 13 that are close to each other. The rotating groove 1 is provided with a rotating groove 2 at the side of the rotating groove 1 away from the guide rail 2 13. The rotating groove 2 is provided with a storage groove 1 on the side away from the rotating groove 1. A locking mechanism is provided in the rotating groove 1. The locking mechanism includes a rotating column 30 that rotates in the rotating groove 1. A rotating plate 31 is fixed on the side wall of the rotating column 30 away from the guide rail 2 13.

[0040] The rotating plate 31 has a limiting post 32 fixed on the outer side of the side wall near the rotating post 30. The axial direction of the limiting post 32 is consistent with the axial direction of the rotating post 30. The rotating groove 2 has an annular rotating groove 3 on the side near the guide rail 13. The rotating groove 1 is directly connected to the rotating groove 2 and the storage groove 1. The rotating groove 3 is connected to the rotating groove 2, but the rotating groove 1 is not directly connected to the rotating groove 3. The limiting post 32 rotates in the rotating groove 3.

[0041] It should be noted that: a lead screw is provided inside the guide rail 2 13, and a slider slides on the outside of the lead screw. The slider slides inside the guide rail 2 13. A drive motor is fixed to the end of the lead screw away from the wall 10. The drive motor is fixed to the ceiling 11. A rotating rod is rotated at the bottom of the slider. The end of the rotating rod away from the slider rotates on the baffle 20 located at the top. When the drive motor drives the lead screw to rotate, it drives the slider to slide synchronously, thereby pulling the baffle 20 to move along the guide rail 1 12 to realize opening and closing.

[0042] Please see the appendix Figure 1 To be continued Figure 7 The present invention provides a technical solution: a limiting post 33 is fixed on the side wall of the rotating plate 31 away from the rotating post 30. A slide rail spring 34 is sleeved on the outer arc wall of the limiting post 33. Another limiting post 33 with the same structure is sleeved on the end of the slide rail spring 34 away from the limiting post 33. The other limiting post 33 is fixed on the inner side wall of the storage groove away from the rotating post 30. The slide rail spring 34 is V-shaped and the middle part of the slide rail spring 34 is axially arranged away from the rotating plate 31.

[0043] A slot 1 is provided at the center of the side wall of the rotating column 30 away from the rotating plate 31. When the two rotating columns 30 abut against each other, the two slots 1 are joined together to form slot 2. The longitudinal section of slot 2 along the radial direction of the rotating column 30 is a regular polygon.

[0044] It should be noted that: the rotating column 30 is semi-cylindrical and the rotating plate 31 is semi-disc. When the limiting plate 15 and the locking mechanism on the guide rail 12 abut against each other, the two rotating columns 30 combine to form a cylinder and the two rotating plates 31 combine to form a disk. The slots 1 on the rotating column 30 are also spliced ​​together to form a polygonal slot 2.

[0045] Insert the tool that matches the polygonal slot two into the polygonal slot two and rotate it clockwise. The two locking mechanisms rotate in opposite directions, and the limiting post 32 on one side will rotate into the rotating groove 3 on the other side to form a fixed position. At the same time, under the action of the slide rail spring 34, it will not loosen when subjected to vibration.

[0046] Working principle:

[0047] When the limiting rod 1 24 and the limiting rod 25 are inserted into the hollow cylinder composed of the fixing ring 1 22 and the fixing ring 23, the fixing rod 26 enters the groove 1, and the inclined surface of the end of the limiting rod 3 29 abuts against the arc wall of the stop block 28, forcing the limiting rod 3 29 to retract. When the limiting rod 3 29 passes the stop block 28, the limiting rod 3 29 pops out under the action of the return spring 2. In this state, since the side walls of the limiting rod 3 29 and the stop block 28 that are close to each other are both vertical planes, the limiting rod 1 24 and the limiting rod 25 are locked to each other at this time, and the limiting block further prevents the limiting rod 1 24 or the limiting rod 25 from leaving the hollow cylinder.

[0048] To release the fixation, simply continue moving the first limit rod 24 or the second limit rod 25 toward the side that is closer to each other. When the third limit rod 29 abuts against the first stop 27, the inclined surface at the end of the third limit rod 29 abuts against the edge of the first stop 27, forcing the third limit rod 29 to retract. Here, the friction between the third limit rod 29 and the first stop 27 is less than the elastic force of the first return spring. However, when the first return spring is compressed to a certain extent, the thrust transmitted from the third limit rod 29 is greater than the elastic force of the first return spring, causing the third limit rod 29 to pass over the first stop 27. At this time, move the first limit rod 24 or the second limit rod 25 toward the side that is farther away from each other, and the third limit rod 29 will carry the first stop 27 to move in the opposite direction.

[0049] When stop block 1 27 and stop block 28 abut against each other, limit rod 3 29 can slide unimpeded along the outer arc wall of the two, and limit rod 1 24 and limit rod 25 then separate, and stop block 1 27 is reset under the action of return spring 1.
